Home Cinema Installations and Sounds Transmission Through Doors

The reference level about a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not difficult to listen to, in a correctly designed home cinema room.

A problem occurs though, when we face the challenge of keeping the noise inside the cinema room. In non commercial installation, quite often we find bedrooms and other living areas to be right next to the home cinema environment. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.

However, doors generally been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door determines its resistance to the passage of any sound waves. A door’s ability to reduce noise is written by its Sound transmission Class. This means, the higher in the Class the better the efficiency.

One more problem arises though; Sound waves can travel through any opening with very little impairment. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as a much larger leak. This acoustic property of sound could be an oversized problem in a residential cinema audio visual installation Hertfordshire, where high quality construction is required. Can be where acoustical gaskets come into engage. A home cinema door, so as to be effective, the seals around the head, jamb and sill must be complete and air-tight.

In other words, the actual of the acoustical gasket in an at home cinema installation, would see how close the particular sound performance of the door, stomach to the published requirements. A hi-end home cinema design should take every piece of information into consideration, to ensure a hi-end acoustical result.
